The firmer tires used on electric vehicles, to make them more efficient, 
might make the situation worse.

ps: Just to get this back to Link's area of interest, the Internet could 
be used to implement road use charges, to better reflect the usage of 
vehicles. Perhaps electric scooters could also weigh the rider and 
impose a suitable penalty for increased road wear. ;-)
